The best visualization for the flatness of planetary systems is that they are somewhere in between that of a pancake and that of a crepe. Gives food for thought next time you eat at your local IHOP.
Hubble has been as big a revolution as was the first telescope built by Galileo in 1610. It has profoundly changed our view of the universe and our place in it. Now, 22 years into its life, it has outperformed even the most optimistic predictions of its builders.
Apophis' chief claim to fame is that it briefly achieved the highest level ever measured on the Torino Impact Hazard Scale before it was downgraded. Nevertheless, it still has a one in 250,000 chance of hitting Earth on its second visit.
If you want to believe the universe is out to kill you, it's easier to do it with a random piece of space rock than with a Mayan death ray from the black hole in Sagittarius.
A recent study estimated that 99% of the population of America and Western Europe never see a clear night sky unobscured by dust, smog and light pollution. In cities such as London, the firmament simply never darkens. Now imagine yourself reclining in a desert oasis on a clear moonless night, the air still and silent as you stare up at velvety black heavens carpeted with stars. Linger long enough, and you'll see satellites inching across the sky and glimpse shooting stars.
Astronomers see UFOs. In the U.S., astronomers who observe UFOs fear ridicule from other scientists and the press. Despite the aura of illegitimacy around UFOs, the data indicates that astronomers even report UFOs at noticeably greater rates than laypeople.
When I got an email saying that Dr. Charles Elachi would be speaking at MIT on September 17th, I knew I didn't want to miss it.
Travel to a location far from any major city or other sources of terrestrial light--preferably to the top of a mountain somewhere, surrounded by natural habitat, rather than villages or towns. Stay up after dark, and spend some time looking at the night sky.
Dance in the round is rich with possibility. Each viewpoint offers a chance to present a different aspect of the moving body, with no one angle being definitively "right" or "best."
From an iPhone (or Android), consumers will be able to request an image from the satellite, orbiting 600 kilometers above the Earth. They will be able to send a message to SkyCube from their phone as well.
The Golden Ratio, usually denoted by the Greek letter ϕ (phi), has the propensity of popping up where least expected, in a variety of natural phenomena and works of art.
It is much more fun and challenging and honest to try to explain UFOs with science and the laws of physics. To attribute them to some mysterious or supernatural "unknown" is intellectually lazy.
Arriving as it will on the heels of the Olympics, Curiosity will continue the flow of good kind of news we have been witnessing from London to the people of Earth. The mission represents the kind of news we want to hear and see, the kind of news that inspires us.
"What's anything without a trip to Mars?," asked NASA's Eric De Jong Tuesday night on stage at the Academy of Motion Picture Arts and Sc...
Unless you think that life is highly improbable -- that in a galaxy filled with planets and the basic molecules of biology, life only seldom appears -- then it's hard to believe that all three of these theories will fail.
The cosmos is unquestionably extreme, and the numbers that measure these extremities can at first seem hard to comprehend. On closer inspection, the universe's extremes become not only comprehensible, but vital keys needed to unlock the true wonder and elegance of the heavens.
